Left front caliper won't release
 

Ok here it is. Sometimes after I brake the left front caliper won't release. It doesn't happen all the time either. I've replaced that caliper twice and installed a new proportioning valve. I've checked the hardlines and there is nothing wrong with them. An X-GM employee told me that sometimes the caliper will mechanically bind which is what looks like is happening. Any ideas? Has this happened to anyone else?

have you replaced rubber line that goes to the caliper yet?

The only part of the hydraulic system that I haven't replaced is the master cylinder and the soft lines. I think the next thing after I replace those(or the first thing) is the allen bolts that hod the caliper to the bracket. I think that they are flexing enough to cause problems.

Is the bolt that holds the soft line to the caliper aligned correctly? Is it just on certain types of braking??

I'd have to put a vote towards the rubber line being the culprit as well.

My brother changed his rubberlines and it solved his problems.

Agreed; the rubber line... replace both fronts at the same time; otherwise, you'll surely be doing this job again on the other side soon!

yup, less than a month ago that solved my problem. change those lines.

Here is what happened to me. In the rubber lines there is a liner, when these lines get old that lining acts like a flap. This flap will hold the pressure causing the caliper to continue to brake. Replace the rubber lines! It's easy if you use heat to get the connections loose, don't bend the steel lines or your FUBAR!
